SPECIFICATION forming part of Letters Patent No. 612,739, dated October18, 1898. Application iiled September 7, 1897. Serial No. 650,822, (Nomodel.)

bling, have invented certain new and useful Improvements inHorse-Powers; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

This invention has reference to a novel construction in a sweep-motor,the object being to provide a durable device of this kind which convertsrotary into reciprocatory motion.

The invention consists in the features of construction hereinafterdescribed and specifically claimed.

In the accompanying drawings, forming part of this speciiication, Figurel is a plan view of a motor constructed in accordance with thisinvention and with parts broken away for convenience of illustration.Fig. 2 is a side elevation of the same.

Referring now to said drawings, l indicates a base upon which the motoris mounted and which is provided with two cross-pieces 2. Mounted uponthe rear cross-piece 2 is a plate 3, having an arm 4, that extends toandis secured upon the other cross-piece. The said arm al. serves as asupport lfor the pitman or plunger-rod 5 and is provided with theVguides 6, which confine the pitman thereon. The pitman is provided witha depending Vfinger 7, that extends through a slot S in the arm 4, andconnected with said iinger 7 and in the rear of the cross-piece 2 is aspring 9, that serves to draw the pitman to the rear. Mounted upon theplate 3 is the frame lO, which projects beyond the sides of the plateand between the upper and lower sides of which and at the cornersthereof are mounted horizontally-arranged grooved pulleys l1, that serveas guide pulleys for the master or power wheel l2, said wheelconsisting, preferably, of an arm and spokes, it being noted that it isnot provided with acentral pivot, but is centered by the grooved pulleysll at the corners of the frame and which engage the pe-` tated theprojections force the pitman forwardly against the action of the spring,and when one projection passes to one side of the pitman said springdraws the saine to the rear and in position to be engaged by the otherprojection, so that as the sweep and wheel are rotated a reciprocatorymotion is imparted to said pitman. The forward ends of the frame IO aresecured and braced by means of rods 16 to the front end of the frame 4.

The device is adapted for use Inore especially with baling-presses,although it is understood that it can be used wherever such a power isdesired.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

A sweep-motor comprising a plain disk or master-wheel, horizontalpulleys having parallel peripheral flanges engaging the periph-- ery ofsaid disk for centering and upholding the same, a sweep or power leversecured to the upper face of said disk to clear the grooved pulleys, apitman or plunger-rod and means connected therewith and with the diskfor imparting a reciprocating movement to said pitman or plunger-rod,all substantially as described. i

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.

EDI/VIN LAMBERT.
